To ALL wHoM 1T MAY CONCERN:

Be'it known that'I, C. K. MARSHALL, oiuNew Orleans, parish of Orleans, and State of Louisiana, have invented certain new and useful Improvements in Metallic Horse-Collars; and I do hereby'declare that the Yfollowing is a full, clear, and exact descriptionof the same, reference being had tothe annexed drawings, and .to the letters of reference marked thereon, :in which-n Figure 1 is a front view of 'my metallichorse-collar, showingV hinge-fastening at bottom and strap at to'p. Figure 2 is also a front view of my metallic horsefcollar, showing another mode of fastening 'the same at bottom.

Figure 4, section, at y y, of iig. 2, showing the collar iilled with ,wood or other material.

Figure `5, another device for hinge-fastening." i I Figure 6, another device Vfor strap-fastening. v

Iam aware that various attempts have been made to supersede the use of leather, in whole or in part, in the manufacture of horse-collars, with a view to lessen their expense, and also to prevent the galling of the horse. To obtain those desirable advantages, collars have been madeof felt onfelted cloth, and more recently duck-cloth has been used for the same purpose.

Practical experience has demonstrated the fact thatl the use of such materials does not answer the purpose, as they possess stilbgreater disadvantages than are met with inthe ordinary leather collar.

It is well known that all the collars now inuse, with s'carcely'a single exception, are constructed of materials that will freely absorbthc perspiration and vapor from the horse, yand this, instead of tending in any degree to lessen the chaiing and galling of the horse, experience proves is the very cause which most generally produces it. Moreover, in rainy weather the water will penetrate all'the materials now'in common use, and the straw will become completely saturated, and being closely'packed in the collar, will retain the waterffor a long time. l

,l Among the chief causes which produce galling is the working of the stuffing of the collar into hard .knots or bunches, so as torrender the surface of the collarlumpy, or more unyielding at one point than at another, and it isrwell known that-this lumpy condition of the stuing will -be produced much sooner when liable to become wet, either from perspiration or rain, than from any other cause.

Furthermore, the stuilingrin'a wet or damp condition, rots rapidly, and the pressure of the hamcs on the collar will tend to squeeze the water from the rotten straw, through the collar, thereby staining it, and by the dampness of the straw also Vcause the material to rot. i I

My improvement obviates'all of the foregoing objections, can be manufactured cheaper than any collar now in use, and is also entirely practical. i

My invention consists, iirst, in constructing a horse-collar :entirely of metal; second, in introducing' a system of bracing between the metallic plates; and, third, in attaching to the collar rein-eyes a.nd traceclips, so as to dispense entirely with the usc oi' haines..

My collar being constructed, as it is, entirely ot' metal, caribe made exceedinglylight. Itis cheaper than any material now used for the purpose. It will sustain an immense draught, for it is constructed on the wellknown 'principle of the braced double arch. It is impervious to rain; It does not absorb the perspiration from the horse. It does not gall' the animal, no matter how constant the use or heavy the pull. `Its surface being perfectly smooth and as unyiclding at one point as4 at another, thergrcat cause of chaing and rubbing the horse is removed. i

To enable others skilled in the art to which my invention is applicable' to make and use the same, I will proceed to describe its construction and operation. l v I A A are metal cylindricalplates, of theorin shown in 'gs. 1 and 2, and are of a shape which enables them exactly to Vconform to the contour of the noel; and shoulders of the animal. The platesumay'be made of any suitable metal, and may be made from the shoot, or cast.

When made of .cast metal, they are formed precisely as any other'ordinary casting. When made oi' sheet metal, they may be formed in moulds'with dies, or struck up on any of the machines new used'for this class A of Work. The rear plates are exact counterparts of the front plates-A A, and they may b e united by riveting, brazing, soldering, or seeming. These plates A A, at their lower ends, are united together'by a hinge or link, a, universal joint, strap, and eye, or any otherconvenient means. 'They are left free at their upper ends, and can be united, when desired, by a strap,b, or any other convenient means.

To the front plates A, I attach, by rivets or screws, as shown 'in fig. 4, or otliersuitable means, reineyes, c c, and trace-clips-d d, whi-clrenaliles me to dispense entirely with haines, and with them all the annoyances and disadvantages connected with their-use. The front and rear plates, when broughtv together and united,

forni, as it were, a hollow cylinder, as clearly shown in figs. 3 and 4.

When the same is deemeddesirable, I introduce at different points a double T(:1:)headedl brace, e. rThe cylindrical opening between the plates maybe filled with wood, o r the space may be stuffed with any suitable material, for example, the lignine flour patented to me, November 12, 1867. When articles of such character,

however, are used, the same must be thoroughly packed between the plates. In very severe weather, a thin sheet of leather may be attached to the under side ot' the collar, so that when the coll-ar is applied-to the neck` 0f the animal, the metal willnot come in immediate contact therewith.

The upper plate A may be either plain or corrugated. v Collars constructed of sheet metal are susceptible of the highest degree o`i` ornamentation, and maybe faced with patent leather, or they may be galvanized and plated.

It will readily occur to-any one familiar-:with the'art that collars constructed on my plan may be made beautiful-and artistic in the extreme. l Having thus vfully described my invention, what I claiml therein as new, and desire to secure by Letters Patent, is- Y i I. A 4metallic horse-collar, constructed substantially as described, and for the purpose specified. 2. Bracing the metallic plates, of which the horse-collar is formed, substantially as described, and for-the purpose specified.

3. `'lhe combination ofthe plates A A, reinmyesf c c, and tracefclips d UZ, when the same are constructed and arranged substantially as described.

, In testirnonywhereof, I have signed my name to this specification in the presence of two subscribing witnesses. f e. K. MARSHALL. Witnesses:
